Faulting and natural fracturing across the DJ Basin: impacts on production from Hereford field, northern Colorado
… on the structural characterization of the Hereford Field in the Northern DJ Basin with the main objective of identifying the controls on geologic heterogeneity that impact well performance; the understanding of the geologic controls can then be leveraged to optimize subsequent drilling and …

Evaluation of phenotypic and genetic trends in weaning weight in Angus and Hereford populations in Virginia
… weight records of 29,832 Angus and 15,765 Hereford calves born during 1953 through 1983 in Virginia were used to evaluate phenotypic and genetic trends for adjusted weaning weight (AWWT), weaning weight ratio (WWR) and deviation of AWWT from the mean AWWT of the contemporaries (DEVN). Two …

Comparison of maternal performance of reciprocal crossbred cows
… reciprocal two-breed cross cows between Angus, Herefords and Shorthorns was compared in 249 matings over a four year period. These cows were mated to bulls of the same three breeds to produce three-breed and baekcross calvea. Shorthorn x Angus cows (sire breed first) weaned l7.S~ fewer calve. …

A study of growth rate and type score of offspring of four different sires in Hereford cattle
A study of growth rate and body type of calves of both sexes; estimates of heritability of growth rate and body type; and the effect of data of birth on growth rate was made on 76 calves in the same herd sired by four unrelated bulls. The calves were scored for body types at birth, weaning and the …

Effects of inbreeding and estimation of genetic progress upon preweaning traits in beef cattle
Data on 1571 Angus, 1737 Herefords and 1313 Shorthorns from the BCRS, Front Royal, Va. from 1951 through 1969 (excluding 1960) were used to study the effect of inbreeding on birth and weaning weights, ADG birth to weaning and type score at weaning, and estimate genetic progress from selection in …

Comparison of expected and actual progeny growth differences in crossbred calves
The growth performance of Angus-Polled Hereford F<sub>1</sub> calves was compared to the expected progeny differences (EPD) estimated by the American Polled Hereford Association to evaluate the usefulness of EPD estimates for improving commercial beef production. Polled Hereford sires were selected …
